Assembly: NationalInstruments.RFmx.Cdma2kMX.Fx40 (in NationalInstruments.RFmx.Cdma2kMX.Fx40.dll) Version: 24.5.0.49286 (24.5.0.49286)

Syntax

public int FetchEvm(
	string selectorString,
	double timeout,
	out double meanRmsEvm,
	out double maximumPeakEvm,
	out double meanFrequencyError,
	out double meanMagnitudeError,

Public Function FetchEvm ( 
	selectorString As String,
	timeout As Double,
	<OutAttribute> ByRef meanRmsEvm As Double,
	<OutAttribute> ByRef maximumPeakEvm As Double,
	<OutAttribute> ByRef meanFrequencyError As Double,

) As Integer

Parameters

selectorString  String
Specifies a selector string comprising of the result name. If you do not specify the result name, the default result instance is used.
timeout  Double
Specifies the timeout for fetching the specified measurement. This value is expressed in seconds. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the method waits until the measurement is complete.
meanRmsEvm  Double
Upon return, contains the mean averaged RMS EVM of the received signal. This value is expressed as a percentage.
maximumPeakEvm  Double
Upon return, contains the maximum peak EVM of the received signal. This value is expressed as a percentage.
meanFrequencyError  Double
Upon return, contains the mean averaged frequency error of the received signal. This value is expressed in Hz.
meanMagnitudeError  Double
Upon return, contains the mean averaged magnitude error of the received signal. This value is expressed as a percentage.
meanPhaseError  Double
Upon return, contains the mean averaged phase error of the received signal. This value is expressed in degrees.
meanChipRateError  Double
Upon return, contains the measured mean chip rate error of the received signal. This value is expressed in parts per million (ppm).

Return Value

Int32
Returns the status code of this method. The status code either indicates success or describes a warning condition.
